Comment 2 for bug 1370077

Yes, either Nova has to be patched so that it assumes that value or Neutron port binding db mixing be patched so that if plugin does not set the attribute it gets the default value.

Related to this and more generally: What does it actually mean when a plugin supports an extension that introduces a bunch of attributes (like the 'bindings' extension)? Should one assume that the introduced attributes are not necessarily returned in get_<resource> requests?
